Previously, it was thought that only dogs that were long-haired were more resistant to heartworms because of the high difficulty of mosquitoes (which bring the worms) to penetrate through the dogs’ hair. Since then, it has been proven that this is not true.
Mosquitoes even have a hard time penetrating through short-haired dogs. Actually, mosquitoes feed on the abdominal region of the dog. That is why both long-haired and short-haired dogs are susceptible to heartworm infection, since both types have little hair on this region. Some mosquitoes also feed on the muzzle area or the ears where the dog’s hair is quite matted down.
Dog heartworm is a common disease among canines in the United States. Discovered in 1856, the worms mainly live in your dog’s heart and major blood vessels.
The worms, especially on worst cases, seriously impair the heart’s operations. Worse, they could also clog your dog’s blood vessels. These infections result in loss of body weight, chronic cough, dropsy, shortness of breath, chronic heart failure, vision disturbances, and ultimately death.
Since heartworm symptoms vary among dogs, it’s best to have a veterinarian check your dog to provide a final analysis. Early treatment of heartworm is vital.
Most dogs show visible symptoms only when the disease has reached the point where it would be almost impossible to be cured by treatment. To help you see early symptoms and to hopefully save your dog, look out for these signs:
- Dogs that have been quite active usually tend to tire easily.
- Dogs that otherwise appear healthy usually gasp for breath.
- Your dog may develop a cough.
- Dogs bred for hunting may no longer keep up with rapid chases and usually fall from exhaustion.
- In some rare instances, the dog experiences convulsions, jaundice, and vision problems.
- Death is typically preceded by emaciation.
Heartworm infection can be treated through chemical therapy if diagnosed early. Most of the chemical treatments kill the worms over some period of time. Killing all the worms in one swoop is no better: If all the heartworms were killed in just one treatment, the dead bodies would deposit in the lungs and kill the dog.
Remember also that the chemicals used in treating the worms are also as dangerous to your dog as the worms. That is why treating the disease using chemical therapy should be used with utmost care and should be handled by a veterinarian.
There also cases when surgery is needed. In most cases, this can be a feasible option. Consult with the veterinarian about surgical correction or any other method that can cure the infection.
There are also drugs that could prevent your dog from getting heartworms. These drugs attack the parasite in its early stages and stop the worms from being full-blown adults later. This doesn’t mean that your dog would be free from infection. This only means that dogs can still get infected during the season of mosquitoes and yet remain unscathed of heartworms.
Preventative medication using drugs, on the other hand, can cause serious complications if your dog already has heartworm infections in a higher level. That is why the use of drugs should be under the supervision of veterinarians. Taking drugs are also combined with regular blood texts. This has shown to be quite effective in saving many dogs with heartworm infection.
In order for your dog to avoid heartworm infection, protect your pet from mosquito bites especially if there is a high mosquito population in your area or if it is mosquito season. You might want to screen the sleeping quarters of your dogs to avoid repeated bites. Repellent sprays can also be used, but these only have limited effects.
You might also want to consult your vet fro preventive medication. In addition, you might want regular blood tests on your dog to assess early symptoms of infection. This is quite tricky, especially if the symptoms of heartworm infection could not be seen immediately.
In short, your dog which looked healthy may be having early symptoms of heartworm infection. It would be best that you have him checked y your vet..
